I bought a Lenovo C630 laptop. It is the absolute worst. Apparently it has some flip-around touch pad feature where the user can tilt the screen all the way back. But it’s so poorly manufactured and cheap that the hinges that connect the screen to the computer are already worn out.
I’ve never even flipped the screen more than 100° back, but the screen flickers all the time to the point it either goes black or I need to turn it off.
It’s trash, don’t buy a Lenovo!
